Implementing Data Change Notification

Follow the syntax desribed in this section to implement DCN with payload, DCN without payload, and WF-DCN.

• Invoking upsert and delete Operations Using Data Change Notification
  Data change notifications (DCNs) with payload directly update the Unwired Server cache, either with the built-in, direct cache-affecting operations :upsert (update or insert), or with :delete.
• Extending Data Change Notification to Mobile Workflow Clients
  Mobile Workflow data change notification (WF-DCN) requests enable you to process the general DCN request and send notification to the device to keep the workflow application synchronized with the enterprise information system (EIS) when a change to the EIS occurs.
